1. is 7.52 :) so easy lol
The sum of two rational numbers will always be <u>rational</u>
<u></u>
, therefore it will always be rational
In form
ax+by=c
slope=-a/b
y intercpept=c/b
so
-3x-4y=-12
a=-3
b=-4
c=-12
slope=-(-3)/-4=3/-4=-3/4
yint=-12/-4=3
slope=-3/4
yint is 3
Answer:
Total ft climbed= 3,011.36
Step-by-step explanation:
<u>Giving the following information:</u>
Total ft= 6,300
Climbing rate= 15% of the remaining height per day
<u>Total ft climbed per day:</u>
Day 1= 6,300*0.15= 945
Day 2= (6,300 - 945)*0.15= 803.25
Day 3= (5,355 - 803.25)*0.15= 682.76
Day 4= (4,551.75 - 682.76)*0.15= 580.35
Total ft climbed= 3,011.36
